Please foresee free space (minimum 50 cm) around the top measurement unit (TMU) to facilitate the
installation of the product-thickness sensor at the antenna side as indicated in Figure 2. The product
thickness sensor is attached to a stainless-steel base plate which is mounted to the two wall-mount
spacers of the HF receiver unit. All units need to be mounted on metal frame which needs to be
accessible from the back to fix the different units.
✓
Mount the computational unit in the vicinity of the TMU and BMU with the cable glands pointed towards
the floor. Please foresee a save and easy access to the TMU, BMU and the computational unit to
facilitate the maintenance on the MICROFREEZE measurement system.

TAINLESS STEEL BASE PLATE FOR MOUNTING THE SENSOR MODULE AND THICKNESS SENSOR
.
✓
The conveyor belt thickness at the electromagnetic-axis should be constant (toothed sections of the
conveyor belt should not be placed in the EM field-of-view).
✓
The HF units and the computational unit should be mounted rigidly on a frame limiting any vibrations
as much as possible.
✓
Make sure there is no electromagnetic coupling from other devices operating in the same HF frequency
range: 2.4-2.5 GHz and 5.725-5.875 GHz. Respect a distance of 1 m from the MICROFREEZE system.
